How to maintain the filter bag?
Protect aging filter bag, filter bag ageing problems are generally use fixed number of year is too long, or is caused by the external environment, for example, dust removal equipment abnormal high temperature lead to bag contraction deformation, hardening and contact acid alkali and other corrosive gas, and chemical reactions that may occur and the surrounding material. It is required that we strengthen the management of the filter work environment, reduce the risk of exposure to harmful substances, regulate the operation of dust removal equipment, and reduce the working temperature.
It is also easy to jam in a cloth bag. Water is the most frequent. So common to avoid improper boot, be careful not to at the time of filter resistance big boot, boot, just below the dew point when there is air infiltration due to the dust collector in the first meet high temperature to low temperature, moisture, are apt to happen.
The repair cost of cloth bag is always the largest proportion in the repair of cloth bag dust collector. So it should be noted that during the adjustment of dust exhaust gas flow, when the flow rate is larger, should increase the flow of the automatic control system, thus ensuring filter can work under stable volume. The inhomogeneity of the intake can cause damage to a certain part of the cloth bag and cause the cloth to perforate. The inlet should be installed in the inlet duct or replaced with a more worn cloth bag. In particular, notice the distance between the cloth bag and the keel. The keel is often broken by a burr when welding. In the other case, because of the long exposure to high temperature exhaust, it is easy to break through the temperature of the exhaust. Change the cloth bag in time.
The daily maintenance and maintenance of dust filter bags as the heart of cloth bag dust collector is very important to prolong the life of bagged dust collector. Dust can be discharged because of the initial layer, damage or failure of the filter bag. 1, if the dust collector of excess emissions cut filter operation pressure is lower than design a lot of time, could be a bag of initial layer is insufficient, may be due to the high bag when filtering velocity, high injection pressure of compressed air, or the filter bag cleaning cycle short, etc. In this case, the cleaning cycle of the cloth bag should be set to the maximum time, and the pressure social stability of the outlet pressure of the dust collector should be improved. But if the collector is discharged after cleaning the bag, it should be examined if the pressure of compressed air is too great.
Here are some things to note about the maintenance of a dust-cleaning bag: 1, dust bag installed after, to start running, when installation should pay attention to bag and skeleton, flower plate hole link must be good, if the connection is bad bag will be damaged first, so that it may affect the use effect of dust collector. This is the initial maintenance of the cloth bag. It's also an important step. 2, will be put into operation after installation is complete, the operation of bag when it is important to note that time to observe the operation condition of the bag, soot cleaning on a regular basis can also maintain the dust bag. 3, in the treatment of high temperature flue gas, try to use high temperature dust bag, high temperature dust bag can better prevent without destroyed phenomenon, also can make the bag of long service life.
